Using Apple’s Dictionary

If you need to look up the definition of a word quickly, here are two ways to do it (on a Mac):

  1. Pull up Spotlight (by clicking the magnifier in the top right of the screen or hit Command-Space) and type in your word. The definition will appear first. You can mouse-over it to see the full definition, or click on it to view in Apple’s Dictionary program.
  2. In Safari, Mail, and most other text-editing programs, select the text and hit Command-Control-D. A pop-up window should appear with the definition of the word.
